are provided in Table 2. Electrical specifications are provided in
Table 3. Typical performance characteristics for the
SMV1145-079LF varactor are illustrated in Figures 1 through 4.
Table 4 summarizes the capacitance of the SMV1145-079LF for
reverse voltages between 0 and 12 V.
The SPICE model for the SMV1145-079LF varactor is shown in
Figure 5 and the associated model parameters are provided in
Table 5.
Package dimensions are provided in Figure 6. Tape and reel
dimensions are provided in Figure 7.
Package and Handling Information
Instructions on the shipping container label regarding exposure to
moisture after the container seal is broken must be followed.
Otherwise, problems related to moisture absorption may occur
when the part is subjected to high temperature during solder
assembly.
The SMV1145-079LF varactor is rated to Moisture Sensitivity
Level 1 (MSL1) at 260 C. It can be used for lead or lead-free
soldering. For additional information, refer to the Skyworks
Application Note, Solder Reflow Information, document number
200164.
Care must be taken when attaching this product, whether it is
done manually or in a production solder reflow environment.
Production quantities of this product are shipped in a standard
tape and reel format.

Note 1: Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other
parameters set at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device.
CAUTION: Although this device is designed to be as robust as possible, electrostatic discharge (ESD) can damage this device. This device
must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body
or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times.
